A notam issued Sept. 1 announced that, beginning Sept. 2, both ADS-B surveillance and TCAS may be unreliable in Virginia, North Carolina, South Carolina, Georgia, and Florida, as well as in airspace extending approximately 200 nautical miles off shore. The situation is expected to last through Oct. 1 as a result of military exercises in the area.<\/em><\/strong><\/p>\n

But similar military exercises in the past have caused no interference with civilian ADS-B or TCAS, and AOPA is asking the FAA to explain both why the notam was issued so late and what has changed to raise these new concerns.<\/em><\/strong><\/p>\n

\u201cWe are working to get answers for our members,\u201d said Rune Duke, AOPA director of air traffic and airspace. \u201cThis notam has caused considerable alarm and much confusion, while giving pilots little time to prepare. The long duration, ambiguous language, and short notice of this notam are all cause for serious concern. We have spoken with representatives of the FAA and the Department of Defense and will continue to pursue this until we get the answers pilots need.\u201d<\/em><\/strong><\/p>\n

This is not my area of expertise, so I encourage readers to do their own research and decide for themselves whether or not this concerning. Given the fact so many people are extremely skittish about \u201csomething happening\u201d this month, I thought it was curious enough to share.<\/p>\n

In a nutshell, it appears that aerial surveillance across much of the East Coast will be impaired until October 1 due to \u201cmilitary activities.\u201d We learn from the NBAA <\/a>(National Business Aviation Association) that:<\/p>\n

TCAS, ADS-B Unreliable in Southeast U.S. Beginning Sept. 2<\/em><\/p>\n

Sept. 1, 2015<\/em><\/p>\n

 <\/p>\n

Due to military activities, the TCAS and ADS-B surveillance may be unreliable in the airspace over Virginia, North Carolina, South Carolina, Georgia and Florida, and extending approximately 200 nautical miles offshore, from 1 a.m. EDT (0500z) Sept. 2 until midnight EDT (0459z) on Oct. 1.<\/em><\/strong><\/p>\n

 <\/p>\n

Pilots are advised that the traffic alert and TCAS may fail to establish tracks on nearby aircraft and may fail to receive traffic alerts (TA) or resolution advisories (RA). Operators should be aware that tracks may first appear within close proximity to their aircraft, and may immediately go into TA\/RA status.<\/em><\/p>\n

 <\/p>\n

Pilots are advised to maintain an increased visual awareness in this area. If operators believe that an aircraft should have triggered an alert, the incident should be reported to air traffic control as soon as possible.<\/em><\/p>\n

 <\/p>\n

This is due to a late notice Department of Defense exercise, and NBAA has voiced its concern to the FAA that these sort of significant impact tests need much more notice to operators in the NAS.<\/em><\/p>\n

The NOTAM numbers are as follows:<\/em><\/p>\n
